This control complies with National Fire Protection Association (NFPA) requirements for temporal pulse sounding

U L

of fire notification appliances.

Alarm Output Supervision

When supervision is enabled, the VISTA-128BPEN monitors the alarm output wiring for open and short circuit faults

while the output is inactive. The system provides a trouble indication (Zone 970) when an open occurs; or when a short

occurs between the Bell (+) and Bell (-) terminal wiring, or between the Bell (+) terminal wiring and earth ground.

NOTE: When supervising the bell output (zone 970), only one device can be connected to the alarm output

U L

(terminals 4 and 5) for UL and Fire installations.

The VISTA-128BPEN indicates the trouble condition regardless of whether the system is armed or disarmed. The zone

displays on the keypads, reports to the event log, and transmits to the central station (if programmed) on Partition 1.

The Contact ID event code is 321, Bell Trouble. The trouble is cleared from the display by entering the user code + OFF.

Wiring the Alarm Output

The wiring of the alarm output depends upon whether you are going to supervise the output or not. Use the appropriate

procedure below for your application.

U L
